KX3 + NaP3

I'm an NaP3 fan, having used it with my K3 for some months. Today, I got
the appropriate cable made up and tried the KX3's I-Q outputs to NaP3.
Setup took basically zero minutes. I just installed the software, using all
the defaults, and started it up. It works great! So far I'm using the
built-in sound card in my desktop (Realtek, 192K sampling) with the basic
MME driver. I'll experiment with other stuff later, but so far so good. If
anyone has thought about trying it but hasn't, I'd say go for it. Big
panadapter display, point-n-click tuning, etc. Up to this point, no hassle,
and zero cost.

Hi,

That's exciting! How wide span can you get with that setup?

NaP3 seems to work well but the display shows vertical lines every 1-2 KHz. These lines disappear when tuning in fixed mode, but reappear when tuning is over. Any idea how to get rid of those lines?

I've seen NaP3 references many times, but I'm completely in the dark about what it
means. Could somebody clue me in, please?

Sodium Phosphide would be Na3P (If it exists)...

NaP3 is a panadapter display program. I know just a little tiny bit about it, such as how to spell it but not much more.

Re: KX3 + NaP3

It's a good option if you want to have a panadaptor display with your KX3. It requires Windows, but I use it on my Mac with VMWare/WindowsXP. It is based on the PowerSDR family, and has been streamlined for use as a panadaptor.

You can find pictures and more info here:

In reply to this post by Phil Hystad-3

NaP3 is more than a panadapter display. It takes the I&Q signals from the KX3 and can do all of the filtering and demodulation that shows on the radio's front panel. It can be set up that so that you see a constant bandwidth +/- the point the radio is tuned. Think FlexRadio, but it's KX3 with neat software.

Re: KX3 + NaP3

In reply to this post by gdaught6

When I connected my KX3 1/Q Output, I had significan "nulls" every 100 cycles, which I do not experience with my K3 using the same computer/cables. Running the audio through my Rigblaster's isolation transformers cleaned up the KX3 signal, which I'm told does not incorporate any isolation due to space constraints.

Taking my Rigblaster Pro into the field is simply not practical, so I have a few isolation transormers on order and I will build a small isolation box. FYI, I tried connecting the Radio Shack ground loop isolator, and it was ineffective while one of their discontinued 1:1 isolation tranformers is effective.

Re: KX3 + NaP3

Make sure you disable stereo audio effects on your KX3 before using digital modes (ie. menu "AFX MD"=>"OFF").

Re: KX3 + NaP3

I wasn't using digital modes, CW and SSB, they were just being displayed on the panadapter via the I/Q output.

I believe DATA modes automatically cancel AFX.

I may be automatically disabling AFX in data modes, but if not, I
will. Just added it to the top of the list.

Jim,
Good idea, but there is bandwidth limitations on some of those
small transformers. You may not get more than about 20 or so KHz before
there is drop off. You might want to do some checking before you go
operational with your scheme. Best of luck with the idea.

Correction, the nulls were on audio, no I/Q. They only exist when using a stereo cable or jumpering the left and right channels together. If I pass a mono signal to the computer, they go away.

I tried an isolation transformer with the combined signals, and they didn't filter it. My guess is the Rigblaster only passes a mono signal.

Turning AFX OFF with a stereo cable does eliminate this.

DATA mode with AFX set to DELAY shows issues with the signal, so AFX does not appear to be getting turned off with the DATA MODE.

I'm guessing phase cancellation with AFX??? But that is speculaton on my part.

Re: KX3 + NaP3

In reply to this post by Barry K3NDM

Yes - good point, quite right. I made a mistake in my post indicating the lines were on the I/Q output, they were on audio...apparetly due to AFX DELAY being on.
